Issue

I want to have a mapview like this suppose my main activity is like this
Here my main activity holds the instance of mapview in main activity and then when I click on it ,then a new activity should be opened with the map activity in android

Solution

You need to have the supportMapFragment in your xml file and get the reference of mapFragment into your MainFragment. The below code explains, How I accomplished the MapView inside Fragment. Write the below XML code in the mapView.xml and then Use the Fragment OnCreateView to get references.

<fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainMap" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="200dp" />

public class MapInFragment extends Fragment implements OnMapReadyCallback {
private View rootView;
private GoogleMap mMap;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    rootView = inflater.inflate(R.layout.mapView, container, false);





    try{
        SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.mainMap);
        mapFragment.getMapAsync(MapInFragment.this);
    }catch (Exception e){
        e.printStackTrace();
    }

    return rootView;
}


@Override
public void onMapReady(GoogleMap googleMap) {
    try {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng croplatlng = new LatLng(Double.parseDouble(latitude), Double.parseDouble(longitude));
        mMap.addMarker(new MarkerOptions().position(croplatlng).title(crop + "Field"));

        //mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(croplatlng,16));

        CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(croplatlng , 16);
        //mMap.addMarker(new MarkerOptions().position(location).title(""));
        //mMap.moveCamera(CameraUpdateFactory.newLatLng(currentLocation ));
        mMap.animateCamera(cameraUpdate,2000,null);
    }catch (Exception e){
        e.printStackTrace();
    }

}


public void onDestroyView()
{
    try {
        Fragment fragment = (getChildFragmentManager().findFragmentById(R.id.mainMap));
        if (fragment != null) {
            FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
            ft.remove(fragment);
            ft.commit();
        }
    }catch (Exception e){
        e.printStackTrace();
    }
    super.onDestroyView();
}

}
